Ford Focus ST Line Edition MHEV (2021)
2021 Ford Focus ST Line Edition MHEV
CarHunch analysed 2,009 real MOT records for the 2021 Ford Focus ST Line Edition MHEV. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2021 Ford Focus ST-Line Edition mHEV is significantly more reliable than average, with a 91.5% first-time MOT pass rate well ahead of the UK's 80% benchmark. The dangerous defect rate of 10.7% is moderate and not a major concern for a buyer, though it warrants a thorough pre-purchase inspection.
At just under 30,000 miles on average, these vehicles are lightly used for their age, which helps explain the strong pass performance. The low failure rate of 0.23 per vehicle combined with moderate advisory issues (2.0 per vehicle) suggests this is a mechanically sound car—focus your inspection on the suspension and lighting systems where advisories typically cluster, but overall this is a solid used buy.
What to check before buying a 2021 Ford Focus ST Line Edition MHEV
Practical pre-purchase checks for this age and model.
- 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
- 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
- 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
